Legal manuscript, signed by the three parties, entitled 'Messrs. Alfred Riehl and W. F. Mohr to W. E. Page Esqre. Agreement for Sale of a Share of certain Royalties arising from Patent applied for and now known as the Boran Lamp'.

On three pages of a foolscap bifolium, supplied by J. Warner & Co., Law Stationer of New Oxford Street, ruled and with red borders. Good, on lightly stained paper. On 25 July 1912 Mohr and Friedrich Hansen 'made an application for a Patent for an improvement in the process of the manufacture of a filament for an electric incandescent lamp (at present known as the "Boran Lamp") accompanied by a complete specification at the Patent Office', but the application has not yet been accepted. Mohr had previously sold the patent to Charles Bertram James, with the foreign rights going to the Industrial Inventions Syndicate Limited. Six points of agreement regarding royalties follow. The document is witnessed by a solicitor, and carries the signatures of the three parties, and their initials at several points in the margins. It carries two red circular stamps on the first leaf, and a Postal Revenue stamp on the second. Also included is a two-page letter from Mohr to Page, dated 30 April 1913, and copies of letters from Mohr to Page of 29 April 1913 and from Mohr to C. B. James of 24 April 1913.
